#4: Red Hat

World Rank: 4

“We affect everybody’s life everyday,” says Red Hat CEO Jim Whitehurst. “Whether you are going to take money out of an ATM, to buy an airline ticket or to do a stock trade you don’t see us, but we are in the background doing all that stuff to make that happen.”

Red Hat, produces, curates and manages open source software. Developers from around the world can use and improve the software. Red Hat makes money by making enterprise supported versions of products that do well in open sourcing and helping big business personalize systems. Imagine if the Windows or Mac operating system that runs your laptop was totally customizable.

The idea of transparency and collaboration infuse the entire business. Even its mission statement was a group effort. “Red Hat is innovative in terms of the products that we have because we work with our customers to innovate,” says Whitehurst. “It’s about community powered innovation. It is not us coming up with what technologies large companies need, it’s us working with Google and Amazon and other large companies to help them solve their own problems.” The only publicly traded open source software company, Red Hat passed $1 billion in revenue for the first time last year.

#5: Intuitive Surgical

World Rank: 6

Intuitive Surgical has installed 2,341 da Vinci Surgical Systems in hospitals around the world. These ergonomically designed robots have four arms, one is fitted with a high resolution 3D camera and the others hold traditional surgical tools. The camera allows a doctor to watch a high-res- live-feed of the patient’s insides. As he operates, the doctor’s hand movements are scaled to the instruments so the whole procedure can happen through a 1-2 centimeter incision. The technology minimizes scarring and recovery time.

In July Intuitive Surgical announced $537 million in second quarter earnings, up 26% from a year prior. Instrument and accessory sales accounted for 30% of earnings.

Rounding out the top ten innovators in America are: #6: Edwards Lifesciences, #7: FMC Technologies, #8: Cerner, #9: Monsanto and #10: Perrigo. For more information on these companies, see our gallery of the ten most innovative companies in America.
